行星借力技术是减小星际探测任务发射能量的有效途径,传统的行星借力模型不能保证探测器借力前后的速度矢量转角达到理想要求。为此,进行了行星借力建模,并基于该模型,推导了探测器飞出借力天体影响球的双曲线超速矢量。针对轨道设计参数的强耦合性,提出了一种全局-局部混合搜索算法,并对地球-金星-地球-火星-木星转移轨道进行了设计。仿真结果验证了轨道模型的正确性和有效性,表明该文方法可以有效地对多次行星借力轨道进行设计。 Planetary leveraging technology is an effective way to reduce the launch energy of the interplanetary exploration mission. The traditional planetary leveraging model can not guarantee that the detector’s levitation speed before and after the levitation can reach the ideal requirements. For this purpose, a planetary leveraging model was established, and based on the model, the hyperbolic velocity vector of the leap-outs celestial body influencing the ball was derived. Aiming at the strong coupling of orbit design parameters, a global-local hybrid search algorithm is proposed and the Earth-Venus-Earth-Mars-Jupiter transfer orbit is designed. The simulation results verify the correctness and validity of the orbital model, which shows that the proposed method can effectively design multiple orbit of the leveraging force.
